Perhaps you’ve heard that radiation levels of the water leaving the Fukushima, Japan, nuclear power plane and flowing into the Pacific Ocean have risen by roughly 9,000 per cent. Turns out, that’s probably putting a good face on it.

By official measurement, the water coming out of Fukushima is currently 90,000 times more radioactive than officially “safe” drinking water.

These are the highest radiation levels measured at Fukusmima since March 2011, when an earthquake-triggered tsunami destroyed the plant’s four nuclear reactors, three of which melted down.

As with all nuclear reporting, precise and reliable details are hard to come by, but the current picture as of July 10 seems to be something like this:

“On July 5, radiation levels at Fukushima were what passes for “normal,” which means elevated and dangerous, but stable, according to measurements by the owner, the Tokyo Electric Power Company (TEPCO).

“On July 8, radiation levels had jumped about 90 times higher, as typically reported. TEPCO had no explanation for the increase.

“On July 9, radiation levels were up again from the previous day, but at a slower rate, about 22 per cent. TEPCO still had no explanation.

“On July 10, Japan’s Nuclear Regulation Authority (NRA) issued a statement saying that the NRA strongly suspects the radioactive water is coming from Fukushima’s Reactor #1 and is going into the Pacific.

We Must Do Something About This Thing With No Impact

“We must find the cause of the contamination . . . and put the highest priority on implementing countermeasures,” NRA Chairman Shunichi Tanaka told an NRA meeting, according to Japan Times.

As for TEPCO, the paper reported, “The utility has claimed it has detected ‘no significant impact’ on the environment.”

Neither the NRA nor TEPCO has determined why the level of radioactivity has been increasing. Both characterize the increase as a “spike,” but so far this is a “spike” that has not yet started to come down.

Here’s another perspective on the same situation:

“10 becquerels per liter — The officially “safe” level for radioactivity in drinking water, as set by the NRA.

A becquerel is a standard scientific measure of radioactivity, similar in some ways to a rad or a rem or a roentgen or a sievert or a curie, but not equivalent to any of them. But you don’t have to understand the nuances of nuclear physics to get a reasonable idea of what’s going on in Fukushima. Just keep the measure of that safe drinking water in mind, that liter of water, less than a quart, with 10 becquerels of radioactivity.

“60 becquerels per liter — For nuclear power plants, the safety limit for drinking water is 60 becquerels, as set by the NRA, with less concern for nuclear plant workers than ordinary civilians.” 60-90 becquerels per liter — For waste water at nuclear power plants, the NRA sets a maximum standard of 90 becquerels per liter for Cesium-137 and 60 becquerels per liter of Cesium-134.

At some of Fukushima’s monitoring wells, radiation levels were in fractions of a becquerel on July 8 and 9. At the well (or wells) that are proving problematical, TEPCO has provided no baseline readings.

“9,000 becquerels per liter — On July 8, according to TEPCO, the company measured radioactive Cesium-134 at 9,000 becquerels per liter. Since TEPCO characterized this as 90 times higher than on July 5, the implication is that the earlier reading (about 100) was less than twice as toxic as the allowable limit and only 10 times more toxic than drinking water for civilians.

“11,000 becquerels per liter — TEPCO’s measurement of Cesium-134 on July 9.

“18,000 becquerels per liter — TEPCO measurement of Cesium-137 on July 8.

“22,000 becquerels per liter — TEPCO’s measurement of Cesium-137 on July 9.

“900,000 becquerels per liter — TEPCO’s measurement of the total radioactivity in the water leaking from Reactor #1. This radiation load includes both Cesium isotopes, as well as Tritium, Strontium and other beta emitters. There are more that 60 radioactive substances that have been identified at the Fukushima site.

A becquerel is a measure of the radioactivity a substance is emitting, a measure of the potential danger. There is no real danger from radiation unless you get too close to it — or it gets too close to you, especially from inhalation or ingestion.

The water flow through the Fukushima accident site is substantial and constant, both from groundwater and from water pumped into the reactors and fuel pools to prevent further meltdowns.

In an effort to prevent the water from reaching the ocean, TEPCO is building what amounts to a huge, underground dike — “a deeply sunken coastal containment wall.” The NRA is calling on TEPCO to finish the project before its scheduled 2015 completion date.

Meanwhile, radiation levels remain high and no one knows for sure how to bring them down, or even if they can be brought down by any means other than waiting however long it takes.

Good time to give up eating fish, especially with children, whose underdeveloped immune system cannot process out such long term effects of contamination.

Bluefin tuna just can’t catch a break. Weeks after it was reported that overfishing had reduced the Pacific population of the fish, which is popular in sushi bars, by over 96 percent, researchers have found trace levels of radiation still lingering in their flesh almost two years after the catastrophe at the nuclear plant in Fukushima, Japan. And the 50 tuna they studied were all caught off the coast of California, 6,000 miles east of Japan, where they were born.

The tuna that registered the highest levels of radioactivity were those that migrated to California in 2011, soon after the accident, but those that migrated in 2012 also demonstrated above-normal levels of radiation. Monte Burke at Forbes writes that the results of the study suggest “there is still a high level of radiation in the waters near the Fukushima plant most likely because, as marine chemist, Ken Buessler, asserts, the plant is still leaking radiation into the ocean nearly two years later.”

Yikes. Doctoral student Daniel Madigan, one of the chief authors of the study also did work showing that tuna were radioactive back in spring of 2012, so it’s not like this is a new phenomenon. But it’s alarming that radioactivity is still popping up. Not that it should be a complete surprise: Bluefin tuna can live to be up to 30 years old and, because they’re near the top of the marine food chain, they’re unusually prone to building up high levels of pollutants in their bodies.

The authors of the study emphasized that the levels of radiation found in the tuna remain “well below safety limits set by the most stringent government regulations” and pose little threat to human health — as they did when radioactive tuna were found soon after the Fukushima accident. On the other hand, if you needed even more of a reason to avoid bluefin tuna, let this be it.

The latest stock assessment of Bluefin tuna in the Pacific released on Wednesday indicates that overfishing has pushed the stock of the giant fish down by a shocking 96.4 percent compared to unfished levels, flying in the face of the conventional wisdom about Bluefin tuna, which says that the Pacific population is much healthier than the Atlantic population.

The assessment, which was released by the International Scientific Committee for Tuna and Tuna-Like Species in the North Pacific Ocean (ISC), pins some of the blame for the precipitous decline on fishermen’s propensity for taking juvenile tuna out of the water before they’ve had a chance to reproduce. About 90 percent of the bluefin caught in the Pacific are juveniles, according to the ISC’s report.

I've observed that people tend to live at one of two extremes in the spectrum of life: those who live on the edge, and those who avoid the edge. Those who live on the edge are hanging out in the most dangerous and unstable places — yet they're also often the most powerful agents of change, because the edge is where change is happening; away from the edge, things are naturally unchanging. ~Thom Hartmann

Local Organic Family Farms

THE SMALL ORGANIC FARM greatly discomforts the corporate/ industrial mind because the small organic farm is one of the most relentlessly subversive forces on the planet. Over centuries both the communist and the capitalist systems have tried to destroy small farms because small farmers are a threat to the consolidation of absolute power.

Thomas Jefferson said he didn’t think we could have democracy unless at least 20% of the population was self-supporting on small farms so they were independent enough to be able to tell an oppressive government to stuff it.

It is very difficult to control people who can create products without purchasing inputs from the system, who can market their products directly thus avoiding the involvement of mercenary middlemen, who can butcher animals and preserve foods without reliance on industrial conglomerates, and who can’t be bullied because they can feed their own faces. ~Eliot Coleman

What is a fact beyond all doubt is that we share an ancestor with every other species of animal and plant on the planet. We know this because some genes are recognizably the same genes in all living creatures, including animals, plants and bacteria. And, above all, the genetic code itself — the dictionary by which all genes are translated — is the same across all living creatures that have ever been looked at. We are all cousins. Your family tree includes not just obvious cousins like chimpanzees and monkeys but also mice, buffaloes, iguanas, wallabies, snails, dandelions, golden eagles, mushrooms, whales, wombats and bacteria. All are our cousins. Every last one of them. Isn't that a far more wonderful thought than any myth? And the most wonderful thing of all is that we know for certain it is literally true...

The whole world is made of incredibly tiny things, much too small to be visible to the naked eye — and yet none of the myths or so-called holy books that some people, even now, think were given to us by an all-knowing god, mentions them at all! In fact, when you look at those myths and stories, you can see that they don't contain any of the knowledge that science has patiently worked out. They don't tell us how big or how old the universe is; they don't tell us how to treat cancer; they don't explain gravity or the internal combustion engine; they don't tell us about germs, or anesthetics. In fact, unsurprisingly, the stories in holy books don't contain any more information about the world than was known to the primitive peoples who first started telling them! If these 'holy books' really were written, or dictated, or inspired, by all-knowing gods, don't you think it's odd that those gods said nothing about any of these important and useful things? -Richard Dawkins
